SAW SET.

I Application filed February To 051 whom it may concern:

1 Be it known that ALoIs SrAUBAoH, a 'citi zen of the United States of America, resid- 111g at Crestline, in'the county of Crawford and State of Ohio, has invented new and usefulImprovements in Saw Sets, of which the following is a specification.

The object of the invention is to provide a simple and. etlicientmanually operable saw setparticularly adapted for small or hand saws although available for use in conned tion with power driven saws, and designed not only to secure accuracy and uniformity in the setting of the teeth but to accomplish the desired object with the utmost facility and rapidity; and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown inthe. accompanying" 1 member 11, said stock being fitted with a removable cap or cover 12 for completing a casing or housing in which the operating parts of the device are enclosed, and the sta tionary grip member 11 being supplemented by a movable grip member 13 pivoted as at 14 to the stock to complete a grip which may be grasped by the hand of the operator and squeezed in order to effect the operation of the plunger 15 carrying the setting bit 16 and mounted in suitable guides '17 and 18 in the stock. The grip members are of transversely telescoping construction to afford a convenient handle by which the tool may be manipulated with the sides thereof inoverlapping relation to prevent pinching of the hand in the operation of the device.

The movable grip member carries an arm 19 which in connection with said grip member constitutes an operating lever having terminal connection with one arm of a bellcrank lever 20 fulcrumed at 21 in the stock and having its other arm connected with the 1, 1923. Serial No. 616,287.

plunger 15. It is preferred to employ a pin and slot connection 22, 23 to connect the arm '19 with the bell-crank lever while'the other arm of said bell-crank lever may be extended through a slot 24 in the rear end of the plunger.

T he stock carries innerand outer jaws 25 and 26 between which the saw blade is adapted to be arranged in connection with the tooth settingoperation, and the space between said jaws is invaded by the biticarried by the plunger 15 and which is movable subject to the retracting action of the spring 27 toward and from an anvil block 28 carried by the outer jaw 26 and revolubly' adjustable to bring difier'ent portions of its operative face into the path'ofthe bit 16. The operative face, of the anvil block is provided with a graduated bevel to agree Withdifferent angular sets of the saw teeth,

and the block is locked in its adjusted posi-' tions by means of a setescrew 29.

'Also in connection with the saw receiving-jaws there are arranged gauge blocks 30 carried by adjusting screws 31. and adapted to be disposed to limit the insertion of the saw blade into the space between the jaws so as to locate the proper portions of the saw teeth in the path of the bit 16.

In cooperative relation with the plunger which as above indicated is actuated by the movable member or the grip there is a saw bladeclamp consisting of a slide 32 mounted in the stock with an tip-turned ear 33 through an opening in which extends the plunger 15, said ear being arranged between a collar 34 and a pin 35 whereby motion is communicated to the side by the plunger. The side extends through a suitable guide 36 at the front end of the stock to also invade the space between the jaws 25 and 26 but with its forward end slightly in rear of the bit 16 so that it serves by contact with the side of the saw blade below the teeth to prevent the tilting of the blade while the setting of the tooth is being effected by the pressure of the bit 16. In other words the clamp which is actuated by the bit carrying plunger serves to resist any tendency of the saw blade to tilt or rock under the pressure of the setting hit upon the tooth of the saw'and insure the deflection of the latter to the proper angle so as to secure uniformity in the adjustment of the saw teeth.

The cap or cover 12 is provided with marthe walls of the stock and a central opening 39 for the reception of a threaded pin,

lll on a partition 41 in which is formed the guide opening 17, said pin being engaged by a nut 4-2 to secure the cap in place.

It will be observed that not only the stool; with its connected stationary grip m.mber but also the movable grip member and the cap or cover may be struck or stamped from sheet metal of a suitable gauge, so as to minimize the costof manufacture of the device without sacrificing the strength thereof.

Having described the invention, claimed as new and useful is 1. saw set having a hollow stock extended to form a stationary grip member, a movable complemental grip member mount ed upon the stock. bit carrying plunger mounted in the stock an anvil block arranged in the path of movement of said plunger, operative connections, between said movable grip member and the plunger a retracting spring in surrounding relation to the plunger. and a saw blade engaging clamp slidably mounted in the stool: and'provided with a right-angularly disposed ear through which the plunger extends, the plunger being provioed ith a transverse pin abutting said ear on one side and with a collar abutting the ear on the other side and; receiving the thrust of the spring. I

2. A saw set having a hollow stock extended to form a stationary grip member, a

what is movable complemental grip member mounted=upon the stock, a bit carrying plunger mounted in the stock an anvil block arranged in the path of movement of said plunger and operating connections between said movable grip member and the plunger, said plunger having a retracting spring and a saw'blade engaging clamp being slidingly mounted in the stock and; provided with an ear engaged with the plunger for movement therewith toward the plane of a saw bladein contact with the anvil block,

the stock and having one of its arms ensaid plunger, the said movable grip member being in transversely telescoping relation with said standard grip member and provided with an arm extending into the stool: and having a pin and slot connection with the remaining arm of the bellcrank lever.

In testimony whereof he atfixes his signature.
